Добрый день всем!Работаю в одной конторе недавно (уже писал об этом). Есть в конторе наследственный линух: Linux localhost 3.14.29-gentoo #3 SMP Wed Feb 11 10:08:14 2015 x86_64 Intel(R) Xeon(R) CPU E5-2609 v2 @ 2.50GHz GenuineIntel GNU/Linux
Пытаюсь оптимизировать конфигурацию его и сети, настроил dhcpd: dhcpd --version
isc-dhcpd-4.3.1 Gentoo-r0, всё нормально работает.

DHCPD_IFACE="br1"
Но вот возникли неожиданные сложности при настройке автозапуска:
rc-update |grep dhcp
dhcpd | default
dhcpd не стартует, ругается, что нет br1, ладно идём в /etc/local.d/local.start, делаем, как делал предшественник, так:
/usr/sbin/eoip
/sbin/brctl addbr br1
/sbin/brctl addif br1 rem1
/sbin/brctl addif br1 rem2
/sbin/brctl addif br1 eno1
/bin/ifconfig br1 up
/bin/ifconfig br1 192.168.0.254/24
/bin/ifconfig eno1 192.168.0.253/24
/sbin/service dhcpd start
/bin/ifconfig br1:1 10.40.10.254/24
/bin/ifconfig br1:2 192.168.1.253/24
Всё равно, при падении питания dhcpd не стартовал. В логе следующее:

Как видите, всё взлетело нормально. :( Чего ему не хватает для нормального старта? Ладно - первый раз, возможно, ещё не поднялся бридж, но второй-то раз он стартует точно после поднятия интерфейса...
И ещё одно - первые 6 строк в логе при старте dhcpd пишутся нормально, а потом (начиная с " WARNING: Host declarations are global." - все строки в логе, касающиеся dhcpd тупо дублируются. :( Кто-нибудь с таким сталкивался?
